A nurse is reviewing the ECG tracing strip of a client who is receiving telemetry monitoring.
The nurse should locate the S-T segment at which of the following locations on the electrocardiographic waveform.

Choice A rationale

Verifying the clarity and color of the eye drops is a critical safety step to ensure the medication has not been compromised. Eye drops should be clear and colorless unless specified otherwise. Any discoloration or particulate matter indicates that the solution may be contaminated or expired and should not be administered, preventing potential harm or infection to the client.

Choice B rationale

Pulling the lower lid down creates a small pocket, or conjunctival sac, which is the proper site for medication administration. This technique prevents the eye drops from immediately flowing out of the eye, allowing for maximum absorption of the medication. It also protects the cornea from direct injury by the applicator, which can be sensitive and easily scratched.

Choice C rationale

Applying gentle pressure to the punctum, the small opening in the corner of the eye, for 30 to 60 seconds after instillation prevents systemic absorption of the medication. This is particularly important for drugs like timolol, a beta-blocker, as systemic absorption can lead to adverse effects on the heart and lungs, such as bradycardia and bronchospasm.

Choice D rationale

Tilting the client's head backward facilitates proper administration by allowing gravity to assist in directing the eye drop into the conjunctival sac. This position also helps to prevent the drop from immediately rolling out of the eye or onto the client's cheek, ensuring the medication is retained in the correct location for therapeutic effect.

Choice E rationale

Administering the prescribed number of drops directly into the conjunctival sac ensures the client receives the correct dosage. The nurse should avoid touching the tip of the dropper to the client's eye or eyelashes to prevent cross-contamination of the bottle. This step is essential for both the therapeutic efficacy and safety of the medication administration. *.

Choice A rationale

Histrionic personality disorder is characterized by a pervasive pattern of excessive emotionality and attention-seeking behavior. Individuals with this disorder often feel uncomfortable when not the center of attention and may use dramatic, theatrical, or seductive behaviors to attract others. They are not typically withdrawn or anxious in social settings.

Choice B rationale

Avoidant personality disorder is characterized by a pervasive pattern of social inhibition, feelings of inadequacy, and hypersensitivity to negative evaluation. The client's statements of becoming "extremely anxious in social gatherings" and never feeling "good enough" for coworkers are hallmark symptoms of this disorder. They actively avoid social situations to prevent rejection.

Choice C rationale

Obsessive-compulsive personality disorder is characterized by a preoccupation with orderliness, perfectionism, and mental and interpersonal control. Individuals with this disorder are often rigid and inflexible. They are not typically described as being socially anxious due to feelings of inadequacy, but rather due to a need for control.

Choice D rationale

Borderline personality disorder is characterized by a pervasive pattern of instability in interpersonal relationships, self-image, and emotions, and marked impulsivity. While individuals with this disorder may experience intense anxiety and fear of abandonment, their core features are related to instability, not a pervasive feeling of not being "good enough" in social settings. .
